CT100 Automated Metallic Time Domain Reflectometer (TDR) Cable Tester / Wire Tester

CT100 and CT100HF Automated Metallic TDR Cable Testers

CT100 Series high-resolution metallic step Time-Domain Reflectometers feature 60 ps (CT100HF) or 150 ps (CT100) system risetime, fast 500 Hz TDR framerate to capture transient conditions, and unprecedented 75 µm (0.003 in) horizontal resolution in typical coaxial cable (VoP = 0.66). With the CT100's 16-bit vertical resolution, you can accurately localize subtle changes in cable impedance signaling early or minor cable damage. Save thousands of full-resolution cable scans on the CT100's internal 4GB flash memory for later review at any horizontal or vertical scale, either on the device itself or on a host PC.

Lightweight (2.0 kg / 4.5 lb) and rugged, with a bright color TFT-LCD screen, the CT100 is fully configurable with user-programmable scripts and sophisticated PC control. The CT100 boasts integrated 10/100 Mb Ethernet, and directly supports many USB peripherals including keyboard, mouse, flash drive, and barcode reader.
